« on: July 10, 2017, 12:47:28 pm »

Hello !!
please, first, watch this video ( https://youtu.be/bSq1ZN1H1EE )

today, my new Arduino Due (official) came.

and i found one problem.

when board connected with USB. i can hear high-freq noise.

i changed few times cables and USB power source ( PC ports, Power banks).

but noise is same. i think it is MLCC maked. im not sure.

is it not normal right ?

Probably just some coil whine from inductors or from some ceramic capacitors. It should be fine.
